Answer: abab.
Step-by-step explanation: to identify the rhyme scheme of a stanza or poem, we need to pay attention to the ending sound of each line, the lines with similar ending sounds, will have the same letter (starting with "a" and going in alphabetical order), and the lines with different ending sounds will have different letters. In the given stanza, the first and third lines have the same ending sounds (power and flower) so they will have the letter "a". The second and fourth lines also have the same ending sounds (but different to the other two lines) so they will have the letter "b" (fame and same). The rhyme scheme would be "abab."
